一、前言新中国成立以来,水电建设事业迅速发展。据不完全统计,目前中国的年水力发电量超过850亿度,约为1949年时的120倍,拥有装机容量10万千瓦以上的已建和在建水电站近60座(均未计中国的台湾省)。随着水力资源的不断开发,建在复杂岩基上的混凝土坝日益增多,因此对复杂岩基的处理和研究成为十分重要的问题。大量的工程实践表明,
I. Introduction Since the founding of New China, hydropower construction has developed rapidly. According to incomplete statistics, at present, China’s annual hydroelectric power generation is over 85 billion kilowatt-hours, about 120 times that of 1949. The hydropower station in China has an installed base of nearly 60,000 hydropower stations under construction with installed capacity of 100,000 kilowatts or more province). With the continuous development of hydraulic resources, the number of concrete dams built on complex rock basins is increasing day by day. Therefore, the handling and research of complex rock basins becomes a very important issue. A large number of engineering practice shows that,
